Example 1:
as shown in fig. 1-2, the present embodiment provides a manufacturing structure for an anchor recess of an anchor end of a precast beam, specifically, the manufacturing structure is a closed annular structure formed by splicing two or more arc segments 1, preferably two arc segments 1 are spliced together, and each arc segment 1 is a semicircular annular structure to form a ring. The manufacturing structure can be fixedly sleeved outside the anchor pocket template, the two arc-shaped sections 1 can be fixedly spliced together in a bolt connection mode, and the manufacturing structure is fixedly connected with the anchor pocket template in a bolt connection mode, wherein a screw hole is formed in the anchor pocket template in advance.
Compared with the prior art that the rubber sleeve is fixed by adopting the binding wire, the manufacturing structure is connected with the anchor pocket template by adopting the mode of bolt connection, so that the firm fixation of the manufacturing structure is greatly improved, and the manufacturing structure is prevented from falling off. The bolt connection mode is more convenient for the installation and the disassembly of the manufacturing structure; meanwhile, the split arc-shaped sections 1 are adopted for splicing, so that the manufacturing structure is conveniently sleeved outside the anchor pocket template, and the operation is more convenient.
Considering that the rubber sleeve is made of rubber, the rubber sleeve is easy to age and damage after long time; and after multiple uses, the rubber sleeve surface can be stained with concrete, difficult clearance. Therefore, the arc segment 1 used in the present embodiment is made of a hard material, preferably a hard steel material. The problems of ageing and damaging the rubber and adhering the concrete are avoided.
Considering that the arc segments 1 are convenient to store and install, in this embodiment, two ends of each arc segment 1 are wedge-shaped ends 101, and the inclination direction and the inclination angle of the wedge-shaped end are consistent, and the inclination angle can be 45 degrees; the two arc-shaped sections 1 are of completely consistent structure, are convenient to store and install, have no sequence and can be mixed for use.
The current process of fixing rubber to anchor pocket templates by binding wires is as follows: one end of the binding wire is used as traction to penetrate through a hole on the anchor hole template and then penetrate into the position of the other hole, and then the two ends of the binding wire are twisted and stirred together. The operation is complicated in view of the above.
Considering the convenience of installing the splicing and manufacturing structures on the anchor pocket templates, besides the two ends of each arc-shaped section 1 are wedge-shaped ends 101, each wedge-shaped end 101 is provided with a through bolt hole 2, each wedge-shaped end 101 is provided with a bolt hole 2, and the bolt holes 2 are matched with the bolt holes 2 on the anchor pocket templates. For example, the bolt hole 2 may be provided with a diameter of 10mm. When the anchor hole template is installed, after the bolt holes 2 at the splicing ends corresponding to the two arc sections 1 and the bolt holes 2 on the anchor hole template are aligned, a bolt sequentially passes through one arc section 1 and the other arc section 1 to be inserted into the anchor hole template, and the anchor hole template is simple and convenient and has short time. And because the binding wire is fixed and must be one and one goes out, so must set up the perforation of pair on the anchor pocket template, this has just increased the work load of trompil, and in this embodiment, only need a bolt just can splice arc section 1 and fix on the anchor pocket template, need not set up paired bolt hole 2, reduced the work load of work progress. And the binding wire can not be reused, waste exists, and the bolt can be reused in the embodiment.
In addition, the direction of the opening of the bolt hole 2 on each wedge-shaped end 101 is parallel to the semicircular diameter of the semicircular arc-shaped section 1, so that after the upper arc-shaped section 1 and the lower arc-shaped section 1 are in butt joint, the connecting line of the two bolt holes 2 and the bolt hole 2 on the anchor hole template is just parallel to the horizontal direction, and the bolt installation is convenient.
Further, the inner end surface and the outer end surface of the arc-shaped section 1 are in inclined transition, and are adapted to the structure of the anchor pocket template; preferably, an arc-shaped inclined transition is formed between the inner end surface and the outer end surface of the arc-shaped section 1, even if the section of the arc-shaped section 1 is semicircular.
The installation step comprises the following steps:
1. and splicing the two arc-shaped sections 1 on the anchor pocket template. The assembly state is that the head of the lapped wedge-shaped end 101 is just in the horizontal direction;
2. aligning the bolt holes 2 on the arc section 1 with the bolt holes 2 on the anchor pocket templates;
3. installing and screwing the bolts;
4. and (5) installing an end die.
And (3) a disassembly step:
1. and removing bolts on the anchor pocket templates.
2. The end form is released and removed.
3. The arc-shaped section 1 is gently pried by a simple crow bar, so that the arc-shaped section 1 can be taken out after loosening.
Wherein the structure of the beam end template is shown in fig. 3, the anchor pocket template is attached to the beam end template,
the manufacturing structure for the groove in the anchor cavity of the anchoring end of the precast beam is not easy to damage, fall off and deform, can be repeatedly used, and is easy to install, detach and clean.
The foregoing detailed description of the utility model has been presented for purposes of illustration and description, and it should be understood that the utility model is not limited to the particular embodiments disclosed, but is intended to cover all modifications, equivalents, alternatives, and improvements within the spirit and principles of the utility model.
